I have given the ring question some thought since I first started seeing the issue raised here several weeks ago. My wife has not worn her wedding ring for the past few years because she had gained some weight and it just didn't fit any longer. She does, however, continue to wear another ring I had given her on the same finger.
For me, I took my ring off a few years ago because I am a wood carver and was getting very raw and blistered where the ring kept rubbing against the inside of my finger. I put the ring back on several months ago when I cut back on the carving.
I have decided that I am going to keep my wedding ring on, regardless of what my wife does and not necessarily to send or reinforce any message to her, but rather to reinforce within myself my committment to my marriage vows and to God. I intend to keep it on even if the D goes through, until such time that God might lead me along another path.
